Applying Pesticides

Introduction to applying pesticides

Applying pesticides delivers insect killers to the target pests. Applying pesticides must be performed professionally so as to diminish environmental pollution and protect operators and other people. The rational applying of pesticides presupposes the knowledge of many biological and chemical aspects of the process.

Applying pesticides in spray form

Pesticides are often mixed with water and sprayed. Applying pesticides is often realized with mechanical sprayers. Sprayers transform pesticide mixtures into droplets. The size range of these particles may vary from large to almost invisible ones.

The spray mixture is forced through spray nozzles under pressure. Large droplets do not drift readily. Small droplets tend to contact more firmly with the target pest. Professionals also use foggers to produce small size particles. Foggers create a motionless zone of pesticide. Foggers are used for enclosed spaces, such as houses.

Aerial applying of pesticides

Aerial applying of pesticides presupposes spraying of pesticides from an agricultural airplane. Agricultural airplanes are specially created for the purpose of applying pesticides. Helicopters are also sometimes used for applying pesticides.

Applying pesticides in dusts

Applying pesticides in the form of dusts is becoming rarer. Dusts may be applied for small area crops and treating grains. Dusts may also be used when application tools are unavailable. Dusts are very small particles and may be easily inhaled or carried by the wind. The risk of inhalation may be reduced by the use of micro granules.

Applying pesticides in granules

Applying pesticides in granules is rather simple near the plant bases and may be performed manually with glove protection. The spreading can be eased with a horn seeder, which reduces contamination of operator. Granules are often prepared for toxic pesticides. However, professionals do not recommend manual application for extremely poisonous compounds.

Applying of pesticides on seeds

Applying of pesticides on seeds is very effective. Pesticides are applied on the seeds for protection of the future plant against possible risks. The coating with a pesticide layer makes the seeds less susceptible to pests. Applying of pesticides on seeds is a target application that protects the seeds from diseases and insects. Applying of biopesticides may also stimulate future crop production.

Applying pesticides at home

Sometimes it is necessary to control insects at home by applying pesticides. Insecticides are sprayed directly on the insects or their nests. Applying pesticides destroys cockroaches, flies, ants, and spiders. Some pesticides in granular or liquid forms are offered to the insects as baits to be eaten. Pesticides against termites are applied into the home foundations. Many home insecticides contain tetramethrin and permethrin that act on the nervous system of insects.
